New features and improvements in NTM
Subscription-based licensing
NTM licenses are moving to a subscription-based model to offer more flexibility and continuous access to updates and support. Existing licenses remain valid.
Visio export format updated
In previous versions, NTM exported maps in the VDX format. Starting with this release, exports are now in the VSDX format. See also VSDX files not supported in Visio for Microsoft 365.
Additional updates
-
Installation wizard updates: Improved pop-ups now provide clearer guidance on upgrades and unsupported scenarios, such as installing NTM and SolarWinds Observability Self-Hosted on the same server.
-
EULA update: End User License Agreement has been adjusted.
-
Setup improvement: Removed an unnecessary password prompt.
Installation or upgrade
For new installations, you can download the installation file from the product page on https://www.solarwinds.com or from the Customer Portal and install NTM on a standalone server.
For more information, see NTM Installation Guide.
Known issues
VSDX files not supported in Visio for Microsoft 365
VSDX files are not supported in Visio for Microsoft 365 due to licensing limitations with Aspose, the third-party library used for file conversion. See New file format in Microsoft documentation.
Resolution or workaround: Open the VSDX files in LibreOffice.
